Thanks for the compliment, I try to get as much detail as I can as you never know when you need to look back on something. I can't tell you how many times I reflect on something and go wonder what I was thinking..this helps that process.
No, I did not use POR15 - I had considered it and ended up going with what I can get locally. I used a zinc based paint...which was fairly difficult to get off even with my blaster. I think do a layer of rustoluem bedliner (same as I used in wheel wells). The liner has a fine texture to it, similar to some to some of the ripple powder coatings I have seen. This was something I picked up from my jeep days and it generally held up pretty well in those condition so it just carried over.
